ecoFLEX - Join the Quiet Revolution

At Vauxhall, we’re spearheading the quiet revolution with our new range of ‘whispering diesels’. Quiet, refined and smooth, they’re a new generation of lightweight and compact 1.6 litre turbo diesels – with Vauxhall’s first ever all-aluminium diesel engine.


They expand Vauxhall’s low emissions ecoFLEX family of engines; your gateway to much more efficient motoring, offering:


  • Improved fuel economy – more miles per tank
  • Lower CO2 emissions
  • Lower Benefit-in-Kind taxation*** for Company Car Drivers
  • Lower Whole Life Costs


Best of all, these cost-saving benefits are achieved without compromising performance or driving enjoyment:


"Vauxhall's new 1.6 CDTi "whisper diesel" is a fantastic engine that lives up to its name. Stick to low revs and it purrs away beautifully. It offers a sharp turn of pace, too."  Auto Express


"I drove the 400 mile round trip from London (to Ellesmere Port) in a Astra Sports Tourer powered by the sweet-revving new 1.6 litre was quiet, smooth, flexible, comfortable and extremely frugal." Autocar


"Vauxhall's 'whisper' name for the engine is a perfect description, as it remains totally hushed and quiet no matter the scenario, and it ably mates to the smooth, slick and positive manual gearbox with six well-chosen ratios." Diesel Car


"The arrival of an advanced new diesel has transformed the Zafira Tourer's fortunes." Auto Express


"...the smooth 1.6-litre CDTi, which effortlessly blends punchy performance with CO2 emissions of 109g/km and near-70mpg." Auto Express


The new design of the 1.6CDTi 16v ecoFLEX Start/Stop engine represents the establishment of a new 'family' of diesel engines for Vauxhall. A high-pressure fuel injection system, Start/Stop technology and a sophisticated Engline Control Unit, all contribute to outstanding fuel economy.









Vauxhall’s ecoFLEX range of engines are available on the following vehicles:


New Insignia with CO2 emissions from 98g/km and MPG up to 76.3 (combined)**

Astra with CO2 emissions from 97g/km and MPG up to 76.3 (combined)**

Corsa with CO2 emissions from 88g/km and MPG up to 85.6 (combined)**

Zafira Tourer with CO2 emissions from 109g/km and MPG up to 68.9 (combined)**

Meriva with CO2 emissions from 99g/km and MPG up to 68.9 (combined)**


Vauxhall’s ecoFLEX diesels can help Drivers and Fleet Operators achieve significant savings. Lower emissions and higher MPG will cut running costs and Benefit-in-Kind Taxation* for drivers, while Fleet Operators can achieve significant reductions in Whole Life Costs.
